Abstract: Experimental investigation was conducted to characterize the responses of High Performance Concrete (HPC) when subjected to uni-axial and biaxial stress. A large number of stress ratios were investigated for compression-tension, tension-tension tests. One kind of HPC (fc = 56.36MPa) was examined with cubic specimens size of 100mm in the test. The specimens were loaded with a servo-hydraulic jack at different stress ratios. The principle stresses and strains of the specimens were recorded, and the failure modes with various stress states were examined. The experimental results indicated that the stress states and stress ratios had significant influence on the biaxial strength and deformation under compression-tension states, but no obvious effect on the strength and deformation under biaxial tension-tension. The test results provided a valuable reference for obtaining multi-axial constitutive law of HPC.
